First-life and second-life battery degradation mode test data

BSEBench status: raw_mirror_pending_validation

This repository is a raw mirror of the Mendeley Data dataset Test_Data from Sadia Tasnim Mowri, associated with the University of Warwick. The source description states that the dataset was created to study the influence of first-life degradation mode on second-life performance and degradation, with first-life cells brought to around 80% SoH and then evaluated in second-life application.

Observed Raw Signals

Battery test CSV files and MATLAB v5 .mat files sampled from the mirror expose channels including Step, Status, Step Time, Prog Time, Cycle, Cycle Level, Procedure, Voltage, Current, AhAccu, AhPrev, WhAccu, Watt, and LogTemp001. Units in sampled files include seconds for step/program time, volts, amps, amp-hours, watt-hours, watts, and temperature channel T1. Source metadata in sampled files includes instrument/test fields such as measurement ID, battery name, circuit, program, start/end time, and test section.

The folder structure includes first-life cycling, first-life RPT, second-life cycling, second-life RPT, cross-sectional SEM/EDX, and surface SEM/EDX files.

Validation Status

This is a raw mirror for BSEBench ingestion. It has not been cleaned, normalized, split, or evaluated for benchmark conclusions. No performance, SOTA, or leaderboard claims are made.
